The public demand for urban green growth (UGG) varies greatly due to climate conditions, resource endowments, geographical location; thus, understanding the coupling relationship between public demand and government supply is important to optimize government investment. This paper aims to evaluate the coupling coordination of UGG between public demand and government supply. An index system consisting of six aspects, including environment, society, economy, population, production and life, was used to evaluate the government supply. Meanwhile, citizens' demand was measured by the satisfaction for the six aspects. The coupling coordination degree model (CCDM) was established to analyze the government supply and public demand for UGG, and it was tested in the case of Shandong Peninsula urban agglomeration in China. The results indicated that citizens of Shandong Peninsula are basically satisfied, and the satisfaction for the environment, population and life is higher than the average value. From 2015 to 2019, the government supply level shows a trend of rising first and then declining, of which environment has been always at a high level for the five years. The coupling coordination degree of UGG shows the supply and demand in different cities of urban agglomerations is unbalanced, and the overall value of the eastern coast is higher than that of the western inland area. Moreover, the concept of relative satisfaction was put forwards, which is of great significance for regional policy. To improve UGG for a city, determining optimization objectives base on their evaluation results of coupling coordination degree and relative satisfaction is important, as well as the possible external reasons for the low coupling coordination degree.
公众对城市绿色增长（UGG）的需求因气候条件、资源禀赋、地理位置等因素而有很大差异；因此，了解公众需求和政府供给之间的耦合关系对于优化政府投资至关重要。本文旨在评估公众需求和政府供给之间的 UGG 耦合协调度。构建了一个由环境、社会、经济、人口、生产和生活六个方面组成的指标体系来评估政府供给，同时用六个方面的满意度来衡量居民的需求。建立了耦合协调度模型（CCDM）来分析 UGG 的政府供给和公众需求，并在山东半岛城市群的案例中进行了验证。结果表明，山东半岛居民基本满意，对环境、人口和生活的满意度高于平均值。2015 年至 2019 年，政府供给水平呈现先升后降的趋势，其中环境在五年内一直处于较高水平。UGG 的耦合协调度显示城市群内不同城市的供给和需求不平衡，东海岸的整体价值高于西部内陆地区。此外，还提出了相对满意度的概念，这对区域政策具有重要意义。为了提高城市的 UGG，根据耦合协调度和相对满意度的评价结果确定优化目标，并找出低耦合协调度的可能外部原因非常重要。
